2. The forest conditions and consequently forests are less xerophytic 
and tropophytic during the dry season; though the deciduous habit is 
present, no trees are deciduous throughout the entire dry season. This 
brings the forest more nearly in accord with Schimper’s tropical rainy 
forest than the Bambusa-Parkia formation. g 
3. The two-story vegetation gives prominence to certain dominant 
species, among which members of the Diplerocarpacee predominate both 
in number and actual volume. 
4. The development of plank-buttresses is often associated with the 
dominant trees. 
5. The great floyistic complexity of the forest is in striking contrast 
with that of temperate forests. 
6. Within the formation, various physiographic situations support 
different types of vegetation. ‘The mesophytic slopes and narrow terraces 
support the climax vegetation, the rocky, flooded terraces are unstable, 
and the exposed ridges a more or less xerophytic vegetation.
